Description

BW-4040XLFR Anti-Fouling RO Membrane Element for Reclaimed Water and Wastewater Reuse

The BW-4040XLFR FR Series anti-fouling reverse osmosis membrane element is specially designed for complex feed water conditions, reclaimed water, wastewater reuse, and high-fouling industrial RO applications. With advanced anti-fouling membrane surface technology and a 34-mil wide feed spacer, this membrane helps reduce fouling, improve cleaning efficiency, and maintain stable performance in demanding water reuse projects.

In industrial water treatment and wastewater reuse systems, membrane fouling is one of the most common causes of unstable operation, increased pressure drop, frequent chemical cleaning, and higher operating costs. The BW-4040XLFR anti-fouling RO membrane element is engineered to solve these problems by improving membrane surface hydrophilicity, optimizing surface charge characteristics, and reducing the adhesion of organic contaminants, colloids, suspended solids, and microorganisms.

This makes the BW-4040XLFR an ideal solution for customers who need a reliable anti-fouling RO membrane for reclaimed water, municipal wastewater reuse, industrial wastewater reuse, and RO concentrate treatment with feed salinity below 10,000 mg/L.

High Salt Rejection Stable salt rejection up to 99.6% under standard test conditions.
34-mil Feed Spacer Wide feed channel improves flow distribution and cleaning efficiency.
Anti-Fouling Surface Enhanced hydrophilicity helps reduce organic and biological fouling.
Low Pressure Drop Designed to reduce pressure loss between feed water and concentrate water.
